CVE-2025-9072 is a medium-severity vulnerability affecting Mattermost versions 10.10.1 and earlier, 10.5.9 and earlier, and 10.9.4 and earlier. It stems from improper validation of the redirect_to parameter, enabling an attacker to craft a malicious link. If a user authenticates via SAML after clicking this link, their session cookies could be exfiltrated to an attacker-controlled URL. The vulnerability has a CVSS score of 5.4, indicating a low-privilege attack requiring user interaction over a network, with potential for low impact on confidentiality and integrity. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
